We didn't need any of the mobile functionality or the other bells and whistles, but we still had to pay for them. Zello is secure, private, and auditable End-to-end security Zello uses the highest industry standard encryption, securing communications from end-to-end. Were bringing instant voice communications to millions of frontline workers, empowering them to build a better world. With no need for expensive specialized equipment or tower leases, you can finally afford to give everyone a voice. Those folks use it like a digital version of two-way radios, or the old Nextel PTT phones. ZelloвЂ™s push-to-talk walkie-talkie app lives on your phone, delivering unlimited and secure private channels and crystal clear broadcasts over cell networks and Wi-Fi. It's designed and priced for larger organizations who need it for managing fleets or large mobile teams, think trucking dispatchers, or managers of large field staffs. You would think it wouldn't be hard to find an IP-based version of the old-school intercom, like on Mad Men (but with way less sexual harassment) where you can push a button and say something to someone in a different office, rather than forcing their phone to ring, or waiting for them to see and answer an IM, but this isn't just the best option, it's the only one I found. Cons: Its connection is very spotty and Im. This is the only app I could find anywhere that provides us with what is essentially an intra-office intercom. Pros: I enjoyed being able to instantly communicate with my team in the plant and to either talk or send messages. Sometimes you really need to know if someone is at their desk and available to take a call, but you don't want to interrupt them with a ringing phone and you don't have time to hope and wait for them to see a Slack-like instant message.
